WO 2006/021412 PCT/EP2005/009067 -3 U.S. Patent No. 5,773,475 also discloses additional compounds useful for treating CNS disorders. These compounds are N-benzyl-2-amino-3 methoxy-propionamide having the Formula (Ila): 5 H H H I I I Ar-CHz-N-C-C-N-C-R 1 10 11 1 11 0 CH 2 0

3 15 Formula (Ila) wherein Ar is aryl which is unsubstituted or substituted with halo; R 3 is lower alkoxy; and R 1 is methyl. 20 The patents US 5.378.729 and US 5.773.475 are hereby incorporated by reference. However, neither of these patents describes the use of these compounds for treating tumor pain, in particular bone cancer pain, for treating chemotherapy-induced pain and for treating nucleoside-induced 25 pain. WO 02/074297 relates to the use of a compound according to Formula (Ila) wherein Ar is phenyl which may be substituted by at least one halo, R 3 is lower alkoxy containing 1-3 carbon atoms and R 1 is methyl for the 30 preparation of pharmaceutical compositions useful for the treatment of allodynia related to peripheral neuropathic pain. WO 02/074784 relates to the use of a compound having Formula (la) or/and Formula (Ila) showing antinociceptive properties for treating different types and symptoms of acute and chronic pain, especially non neuropathic WO 2006/021412 PCT/EP2005/009067 -4 inflammatory pain, e.g. rheumatoid arthritic pain or/and secondary inflammatory osteo-arthritic pain. At present no analgesic exists which is highly potent in various pain syndromes. Different mechanisms leading to inflammatory or neuropathic pain make it difficult to identify compounds which have general analgesic activity. We are only at the beginning of understanding the mechnisms 5 behind different pain syndromes like cancer pain (e.g. tumor-induced bone cancer pain), chemotherapy-induced pain or nucleoside-induced pain which seem all to have various molecular origins. Antidepressents, anticonvulsants or opioids which describe groups of compounds used in pain treatment do not have a common pattern regarding their efficacy in treatment of pain 10 syndromes. This makes it difficult to predict the activity of new compounds in the various pain syndromes and demands a detailed characterization in multiple pain animal models. Neuropathic pain after injury or dysfunction to the peripheral or central nervous system remains a difficult clinical problem for which effective treatments are lacking (Bennett, 1994; Murphy and Reid, 2001). Anticonvulsants are used for the management of some forms of neuropathic pain (Sindrup and Jenssen, 1999; Jensen, 2002). SPM 927 (R-2-acetamido N-benzyl-3-methoxypropionamide) also called harkoseride or ADD 234037 is a novel anticonvulsant drug. It belongs to a series of functionalized amino acids which have been synthesised as a new class of anti-convulsant agents (Kohn et al. 1991). The present studies show analgesic effects of SPM 927 in rat models of cancer pain, in particular bone cancer pain, of chemotherapy-induced pain and of nucleoside analogue-induced pain. Bone is the third most common site of metastasis after lung and liver, and is 15 the primary site of metastatic disease in patients with breast, prostate and lung cancer. The bone lesions that result from metastatic disease also WO 2006/021412 PCT/EP2005/009067 -5 cause severe bone pain, which is a major clinical problem in cancer patients. This type of pain is difficult to treat due to its intermittent, progressive nature, and its aggravation by movement. The predominant symptom in this model of pain is mechanical allodynia. Thermal hyperalgesia and mechanical 5 hyperalgesia has also been demonstrated as measured by the weight bearing difference in the two hindlimbs (Medhurst et al., 2002). Treatment of bone pain in human patients is largely limited to the use of opioids, however the efficacy of potent opioids is minimal, and effective doses produce a range of debilitating side effects. Consequently, there is a clinical need for 10 new therapies that can be used to prevent, treat and alleviate tumor-induced bone pain. Candidate therapies for treatment of tumor-induced bone pain can be evaluated using a rat model as the rat is superior for testing behavioral responses to pain stimuli. One model involves the injection of rat mammary gland carcinoma cells into the marrow space of the proximal tibia 15 using an endpoint of pain assessment (Medhurst et al., 2002), which was performed on Days 7 to 15 following tumor implantation. Chemotherapy-induced pain is a form of neuropathic pain associated with neurotoxic drugs such as vinca alkaloids, e.g. vincristine and is 20 characterized by painful paresthesias and dysesthesias. The clinical antineoplastic efficacy of vincristine is limited by the development of a mixed sensorimotor neuropathy (Casey et al., 1973, Tanner et al., 1998 et al. 1998) that appears to occur in two major stages (Weiss et al., 1974). In the early stage, peripheral axons are damaged by vincristine and the principal 25 symptoms are paresthesias and dysesthesias. In the later stage, which occurs more frequently when higher doses are given for longer periods of time, axons are lost and the principal clinical finding is loss of motor function. The described vincristine rat model seems to reflect the early stage of vincristine-induced chemotherapeutic neuropathy. Whilst the underlying 30 mechanism is not fully understood as yet, it has been described to cause a disorganization of the axonal microtubule cytoskeleton, as well as an increase in the caliber of unmyelinated sensory axons (Quasthoff et al., 2002). These results demonstrated that changes in microtubule structure in WO 2006/021412 PCT/EP2005/009067 -6 nociceptive sensory neurons accompany vincristine-induced hyperalgesia. Painful peripheral neuropathy, induced by nucleoside analogues is becoming recognized as an important source of morbidity in human 5 immunodeficiency virus (HIV) infected individuals (Cohen, 2002). This severely debilitating side-effect may force abbreviation or even discontinuation of AIDS (acquired immunodeficiency syndrome) therapy (Yatvin et al., 1999). This neuropathy is characterized by a sudden onset of intense burning discomfort in both feet sparing the hands at about the 10th 10 week of treatment, which reached severe intensity over a period of days (Dubinsky et al., 1989). The biochemical mechanism underlying this neuropathic remains to be clearly established, although mitochondrial toxicity has been reported to contribute to the development of this neuropathy. Recently, it has been reported that intoxication of rats with anti 1s retroviral nucleoside analogue AIDS therapy drugs (ddC (2',3'-dideoxycytidine), ddI (2',3'-dideoxyinosine) or d4T (2',3'-didehydro 3'-deoxythymidine)), produces enhanced nociception in the rat (Joseph et al., 2004). The mechanism involved appears different from that found to contribute in other models of metabolic or toxic painful peripheral 20 neuropathy, as anti-hyperalgesic drugs effective in these models. Inhibitors of protein kinase A, protein kinase C, protein kinase G, p42/p44-mitogen activated protein kinase (ERK1/2) and nitric oxide synthase have no effect on peripheral neuropathies, and had no effect on nucleoside reverse transcriptase inhibitor-induced hypersensitivity. Intracellular calcium 25 modulators (TMB-8 and Quin-2) are the only agents capable of reversing this hypersentivity of intoxicated animals strongly suggests the role of intracellular calcium in this type of neuropathic pain. Chemotherapy, e.g. treatment with vinca alkaloids like vincristine or with 30 taxol, suramin, cisplatin, carboplatin or oxaliplatin is used for the treatment of cancer and HIV patients. Additionally, HIV or/and tumor patients are also treated with antiretrovirals or antivirals.

Example 15 The effect of systemic administration of SPM 927 was examined in rats in a tumor-induced bone cancer pain model, in a chemotherapy-induced and a nucleoside analogue-induced neuropathic pain model. SPM 927 reduced mechanical and thermal hyperalgesia as well as mechanical and thermal allodynia in these models. It was demonstrated that SPM 927 is useful as an 20 analgesic for treating bone cancer pain, chemotherapy- and nucleoside induced neuropathy and is overall more active than morphine. Materials and methods Bone cancer rat model Cell culture 25 Cells were cultured in medium containing RPMI-1640 (Gibco, 500ml), 10% heat-inactivated fetal bovine serum (Hyclone), L-glutamine (final concentration 2mM, from Gibco) and antibiotic solution (final concentration 10OU/ml penicillin and 100ug/ml streptomycin sulfate, from Gibco). Cells were released from the tissue culture flask by brief exposure to 0.1% trypsin 30 (Gibco) and then prepared for injection as follows: cells were centrifuged for 10 minutes at approximately 1,200 rpm. The resulting pellet was washed WO 2006/021412 PCT/EP2005/009067 - 32 twice in Phosphate Buffered Saline (PBS, Mediatech) containing no calcium or magnesium. Final pellet was re-suspended in PBS and cell count taken using a hemocytometer. Cells were diluted to achieve final concentrations for injection and kept on ice until injection was performed. 5 Surgery After one week of quarantine, either culture media or 3 X 104 syngeneic MRMT-1 rat mammary gland carcinoma cells were injected into the medullary cavity of the proximal tibia of each rat. Procedurally, the animal 10 was first anesthetized with ketamine/xylazine and the right leg area shaved and treated with an iodine solution and cleaned with a 70% ethanol solution. A 1-cm rostral-caudal incision was made in the skin over the top half of the tibia. Blunt-dissection was performed to expose the tibia, ensuring minimal damage to muscles or blood vessels. Using a 23-gauge needle, the tibia 15 was pierced 1-3mm below the knee joint. The needle was inserted at an angle to enable it to be pushed down into the intramedullary canal of the bone. Once a pathway to the intramedullary canal was opened, the 23 gauge needle was removed and replaced by a blunt needle attached to a 5 lil Hamilton syringe. A 3 gI volume of culture medium + vehicle or tumor cells 20 + vehicle was injected into the intramedullary cavity. The cancer cells were slowly injected while simultaneously removing the syringe, enabling the cells to fill the space in the cavity. Following the injection, the injection site was closed using bone wax. The wound was then closed using surgical staples. Post-operative care and observation was carried out until the animal 25 recovered consciousness Behavior measurements Dosing On day 8 or 15, the rats were dosed with a single injection of vehicle, 30 reference compound or test article 20 minutes prior to initiation of testing for mechanical allodynia and approximately 40 minutes prior to initiation of testing for thermal hyperalgesia. Based on the pharmacological activity of SPM 927, the tests needed to be performed no longer than 90 minutes after WO 2006/021412 PCT/EP2005/009067 -33 drug treatment. On day 9, the rats were dosed with reference compound or test article 20 minutes prior to initiation of testing for weight bearing. Nociceptive evaluations 5 On days 7, 8, 14 and 15, pain assessment tests were performed. On day 7, 14, the baseline evaluations were performed. All animals received an i.p. injection of saline approximately 20 minutes prior to baseline testing. On day 8, 15 starting approximately 20 minutes after the test/reference article injection, the animals underwent a series of nociceptive evaluations. The 10 order of testing remained the same for all animals. The animals were first evaluated for mechanical allodynia and then thermal hyperalgesia. The animals underwent testing for weight bearing on day 9 and 15. The animals were first evaluated for baseline weight bearing responses. Following the baseline measurements, rats were injected with the test/reference article 16 and at least 20 minutes later, the animals underwent another weight bearing analysis. Mechanical Allodynia A Von Frey test of mechanical allodynia was performed on the affected 20 (right) hind limb of all animals at baseline (day 7) and on day 8. In this test, the rats were placed in a small plexiglas box with a wire mesh floor. After approximately 10 min habituation, a series of thin nylon fibers were applied from below, through the cage floor, and pressed against the plantar surface of the hindpaw. The rats were unrestrained and un-handled during the test. 25 The diameters of the filaments provided a logarithmic scale of force exerted and thus a linear and interval scale of perceived intensity. The fiber with the weakest force was tested first and is below the normal threshold of detection for most rats. Each successively strong fiber was tested, in each case using a force required to just start to bend the monofilament. When the rat lifted its 30 paw in response to the pressure, the filament size was recorded and a weaker filament was used next. The withdrawal threshold was determined according to Chapman's "up-down" method involving the use of successively larger and smaller fibers to focus in on the withdrawal threshold. Significant WO 2006/021412 PCT/EP2005/009067 - 34 increase in allodynia was based on the comparison of group mean values. Test of Thermal Hyperalgesia The animals underwent testing for thermal hyperalgesia at baseline (day 7, 5 14) and on day 8, 15. Each rat was placed in an individual plexiglas chamber on an elevated heated glass surface for approximately 10 min to habituate. When the animal was at rest, a fiber-optic heat source was guided beneath the glass and aimed at the animal's right hindpaw. The infrared beam was turned on and when the rat lifted or moved its paw, the beam shut off 10 automatically. A timer in the machine recorded the latency to remove the foot, which was taken to signify the time for the animal to detect pain resulting from the heat. If the rat had not moved within 25 sec, the heat source automatically shut off, ensuring that there was no damage to the paw. Only the affected hindpaw was tested. This process was repeated at 15 least twice for each rat, about 3 min apart. If the latencies were within 2 sec of each other, they were averaged. If the latencies differed by more than 2 sec, the rat was tested until there were 2 latencies within 2 sec and these two numbers were averaged. Group means for latency to withdraw the paw were compared across groups with a lower latency indicating more pain 20 sensitivity. Weight Bearing After the animals in groups 4 - 6 were re-randomized to drug treatment groups, on day 9, 15 all animals underwent weight-bearing testing. Weight 25 bearing of affected hind limbs was assessed as the difference in weight borne by the ipsilateral compared to the contralateral limb. Experimentally, the rats were placed in a plexiglas chamber designed so that each hind paw is resting on a separate transducer pad that records the distribution of the animal's body weight on each paw. Five readings from each paw was 30 acquired and then averaged with results expressed as weight bearing difference (WBD; contralateral reading - ipsilateral reading). Rats were allocated eight (8) animals per group based on body weight on the day following arrival. The mean bodyweights for each group was reviewed to WO 2006/021412 PCT/EP2005/009067 - 35 ensure that the mean values and standard deviation satisfy the assumption of homogeneity. Based on the Von Frey testing results on day 8, the animals in groups 4 - 6 were re-randomized to new treatment groups for the weight bearing test to prevent any bias from their previous group assignment. 5 Animals in groups I - 3 remained within their designated groups since these were animals that were naive to the SPM 927 treatment. Vincristine-induced pain model Animal treatment 10 For this study, 86 female Dark Agouti rats (150-200 g) were used (Harlan, Gannat, France). They were group-housed (3 animals per cage) and maintained in a room with controlled temperature (21-22*C) and a reversed light-dark cycle (12h/12h) with food and water available ad libitum. All experiments were carried out in accordance with institutional guidelines. 15 Vincristine intoxication was achieved by daily injection of vincristine (0.15 mg/kg/d, i.p.) from day 1 to 5, from day 8 to 12 and days 15 to 16. On day 17, animals were submitted to the behavioral test and received pharmacological treatment. Vincristine-intoxicated rats were randomly distributed in 5 experimental groups (11 rats per group): 1. 20 vincristine/vehicle, i.p.; 2. vincristine/SPM 927 (3 mg/kg), i.p.; 3. vincristine/SPM 927 (10 mg/kg), i.p; 4. vincristine/SPM 927 (30 mg/kg), i.p.; 5. vincristine/morphine (3mg/kg), s.c. SPM 927 and morphine were respectively injected 30 and 45 min prior to the implementation of behavioral tests. 25 Cold bath test (thermal allodynia) Animals were placed on ice platform submerged approximately 1 cm below the surface of cold water (40C), such that the hairy and glabrous skin of the animal feet was in contact with the cold water. The latency before the first 30 reaction (licking, moving the paws, little leaps) was recorded with a cut off time of 30 s.
WO 2006/021412 PCT/EP2005/009067 - 36 Hot plate test (thermal allodynia/hyperaliesia) Animals were placed into a glass cylinder on a hot plate (Bioblock, France) adjusted to 38*C or 52 0 C. The latency of the first reaction (licking, moving the paws, little leaps or a jump to escape the heat) was recorded. with a cut 5 off time of 30 s. Von Frey hair stimulation test (mechanical allodynia) Rats were placed on a metallic grid floor. The nociceptive testing was done by inserting the von Frey filament (Bioseb, France) through the grid floor and 10 applying it to the plantar surface of the hind paw. A trial consisted of several applications of the different von Frey filaments (at a frequency of 1-1.5 s). The von Frey filaments were applied from filament 10 g to 100 g. The mechanical allodynia threshold was recorded as soon as the animal removed its hind paw the test was stopped and the filament number was 15 recorded. Paw pressure test (mechanical hyperalgesia) The nociceptive flexion reflex was quantified using the Randall-Selitto paw pressure device (Bioseb, France), which applies a linearly increasing 20 mechanical force to the dorsum of the rat's hind paw. The mechanical nociceptive threshold was defined as the force in grams at which the rat withdrew its paw. The cut off pressure was set to 250 g. Data analysis 25 ANOVA followed by post-hoc analysis (Dunnett's test) was used to compare groups of behavioral data in each individual time points. Nucleoside-induced pain Animals, ddC intoxication and experimental groups 30 For this study, 50 male Sprague Dawley (-220 g) rats were used (Janvier, WO 2006/021412 PCT/EP2005/009067 -37 Le Genest-St-Isle, France). Rats were group-housed (3 animals per cage) and maintained in a room with controlled temperature (21-22*C) and a reversed light-dark cycle (12h/12h) with food and water available ad libitum. All experiments were carried out in accordance with institutional guidelines. 5 Intoxication was achieved by a single injection of ddC (50 mg/kg, I.V. in tail vein). On day 10 and day 20, animals were submitted to the behavioral test and 'received pharmacological treatment. ddC-intoxicated rats were randomly distributed in 5 experimental groups (10 rats per group): 1. control/vehicle,ip, 2. ddC/vehicle, i.p.; 3. ddC/SPM 927 (3 mg/kg), i.p.; 3. 10 ddC/SPM 927 (10 mg/kg), i.p; 4. ddC/SPM 927 (30 mg/kg), i.p.; 5. ddC/morphine (3mg/kg), s.c. SPM 927 and morphine were respectively injected 30 and 45 min prior to the implementation of behavioral tests. Brushing test day 20 15 The hair on the legs, flanks, and lower back was sequentially brushed with a cotton-tipped applicator using an oscillating motion (rate of 1-2/s; 30 sec). Brushing was done with no more force than required to move the applicator through the hair such that only the pelage is disturbed. Vocalization and moderate effects to avoid the brushing were counted. 20 Results Bone cancer rat model Mechanical allodynia Fig. 1 depicts group responses to the Von Frey filaments following baseline 25 testing and following drug treatment. The statistical analysis performed using an overall 2-way ANOVA was significantly different for treatment group (p<0.01), but not for baseline vs. treatment effects. One-way ANOVA tests comparing the "cells only" group following "treatment" with each of the treatment groups revealed significant differences in the level of mechanical 30 allodynia for the morphine group (p<0.01), and the 20 and 40 mg/kg SPM 927 group (p<0.05). The 5 mg/kg morphine treatment completely reversed the allodynia that was revealed at the time of baseline testing. In addition, a highly significant difference was demonstrated between the "post-treatment" WO 2006/021412 PCT/EP2005/009067 -38 data for the healthy and tumor-injected "cells only" group (p<0.01). Statistical differences also exist between the baseline values and post-dose values for the "cells only" group and the morphine group (p<0.01). 5 Thermal hyperalgesia The data for thermal paw testing (Fig. 2) on Days 14 and 15 show that the baseline latencies to remove their paws for all tumor-injected groups were. This was confirmed to be highly significant with a two-way ANOVA, in which the drug effect was p<0.0001 and the effect of treatment was significant at 10 p<0.05. The baseline or pre-treatment data were significantly different for the "no cells" vs. "cells only" groups (Dunnett's post-hoc test; p<0.001) with the other groups showing no differences from one another. In addition, the post-treatment groups were different for "no cells" vs. "cells only" (Dunnett's; p<0.001) and "cells only" vs. SPM 927 30 mg/kg dose (Dunnett's; p<0.001). 15 The morphine control group did not show statistical significance although there was a trend indicating that morphine increased the latency to paw removal. Mechnical Hyperalqesia 20 The graph (Figure 3) shows an overall 2-way ANOVA showed significant group differences, 0<0.001. Since weight-bearing differences were defined as the weight borne by the contralateral leg minus the weight borne by the ipsilateral (tumor-injected) leg, a higher number would indicate more weight on the non-affected paw with 0 meaning equal weight distribution on both 25 paws. The baseline data collected showed a positive number, revealing that these animals are all placing more weight on their non-affected paws. In comparison to the "cells only" group, the morphine group and the 40 mg/kg SPM 927 groups showed a significant reduction (p<0.05) in the amount of weight placed on their contralateral paws following treatment, as compared 30 to the "cells only" group. Vincristine-induced pain Cold bath test WO 2006/021412 PCT/EP2005/009067 - 39 As shown in figure 4, a significant statistical difference was seen between the 6 groups (p < 0.05, Anova test). Vincristine-animals treated with the vehicle displayed very short threshold latency in the cold bath test (about 9 s) in contrast with control animals showing a time score about 14 s. 5 Treatment of vincristine-animals with SPM 927 induced a significant increase (p < 0.05, Dunnett's test) in the threshold latency, which became indeed comparable to that of control animals, especially for the treatment doses of 10 and 30 mg/kg. At 3 mg/kg however, the threshold latency was slightly greater than that of vincristine-animals, although statistical difference 10 was not reached. Morphine treatment extended the threshold latency of vincristine-animals to a level far above that obtained from control rats. Hot plate test at 38 0C Figure 5 shows that the threshold latency of vincristine-animals in the hot 15 plate (38 *C) test was significantly shorter than that of control animals (p < 0.05, Dunnett's test). Treatment of vincristine-rats with SPM 927 at 3, 10 and 30 mg/kg induced a significant (p < 0.05, Dunnett's test) increase in the threshold latency. With the treatment doses of 10 and 30 mg/kg, the performance of STZ-rats became comparable with that of control animals. 20 Similarly to SPM 927 at 10 and 30 mg/kg, morphine at 3 mg/kg extended the threshold latency of STZ-animals to a level comparable with that of control rats. Hot plate test at 52 *C 25 As illustrated in figure 6, the paw withdrawal latency of vincristine-rats was significantly shorter than that of control animals (p < 0.05, Dunnett's test). Treatment of vincristine-rats with SPM 927 induced a significant increase (p < 0.05, Dunnett's test) in paw withdrawal latency in as compared with vehicle-treated animals. The effect obtained with the doses of 3 and 10, 30 30 mg/kg was comparable with that of control. Paw pressure test Using the analgesy-meter of Randall & Selitto, vincristine-animals WO 2006/021412 PCT/EP2005/009067 -40 demonstrated a marked decrease in the paw withdrawal latency as compared with the performance of control animals (figure 7). Treatment of vincristine-rats with SPM 927 at the doses of 10 and 30 mg/kg, but not at 3 mg/kg, induced a significant increase (p < 0.05, Dunnett's test) in paw 5 withdrawal latency of vincristine-rats. In this test, morphine treatment did not modify the performance of vincristine-rats (p > 0.05, Dunnett's test). Von Frey Filament test In this test. (figure 8), the paw withdrawal latency of vincristine-rats was 10 significantly reduced (about 20 g) as compared with that of control rats (about 60 g). Treatment with SPM 927 extended the paw withdrawal latency of vincristine rats. The difference with the vehicle-treated group reached the significance level with the treatment doses of 10 and 30 mg/kg (p < 0.05, Dunnett's test). Morphine treatment restored the performance of vincristine 15 rats to a level comparable with that of control group. Nucleoside-induced pain rat model Thermal allodynia As shown in figure 9, a significant statistical difference was seen between 20 the 6 groups (p < 0.05, Anova test). ddC-animals treated with the vehicle displayed very short threshold latency in the cold bath test (about 11 s) in contrast with control animals showing a time score about 20 s. Treatment of ddC-animals with SPM 927 induced a significant increase (p < 0.05, Dunnett's test) in the threshold latency, which became indeed comparable to 25 that of control animals for the 3 test doses, 3, 10 and 30 mg/kg. Morphine treatment extended the threshold latency of ddC-animals to a level comparable to that obtained from control rats. Brushing test at day 20 30 Figure 10 shows the results of brushing test performed on D 20. The animals treated with SPM 927 (at 3, 10 and 30 mg/kg) displayed a significant decrease in the total number of cries (p < 0.05, Dunnett's test). Here again, WO 2006/021412 PCT/EP2005/009067 -41 morphine at 3 mg/kg was able to significantly decrease the total number of cries in the ddC-animals. Von Frey filament test at D10 5 In this test (figure 11), the paw withdrawal latency of ddC-rats was significantly reduced (about 50 g) as compared with that of control rats (about 85 g). Treatment with SPM 927 extended the paw withdrawal latency of ddC rats. The difference with the vehicle-treated group reached the significance level with the treatment doses of 3, 10 and 30 mg/kg (p < 0.05, 10 Dunnett's test) to a level comparable to control group. Morphine treatment at 3 mg/kg restored the performance of ddC-rats to a level similar to control group. Hot plate test at 52 *C at D20 15 As illustrated in figure 12, the paw withdrawal latency of ddC-rats was significantly shorter than that of control animals (p < 0.05, Dunnett's test). Treatment of ddC-rats with SPM 927 only at the dose of 30 mg/kg, induced a significant increase (p < 0.05, Dunnett's test) in paw withdrawal latency in as compared with vehicle-treated animals. The effect obtained with the doses 20 of 3 and 10 mg/kg was comparable with untreated vehicle group. Following morphine treatment, the performance of ddC-rats became similar with that of control animals. Paw pressure test at D10 25 Using the analgesy-meter of Randall & Selitto, ddC-animals demonstrated a marked decrease in the paw withdrawal latency as compared with the performance of control animals (figure 13). Treatment of ddC-rats with SPM 927 at all the 3 doses of 3, 10and 30 mg/kg induced a significant increase (p < 0.05, Dunnett's test) in paw withdrawal latency of ddC-rats. Again 30 morphine treatment increased the performance of ddC-rats (p < 0.05, Dunnett's test).
WO 2006/021412 PCT/EP2005/009067 -42 Conclusion Systemic SPM 927 produced a dose-dependent anti-allodynic and anti hyperalgeisc effect in a rat model of bone cancer pain, chemotherapy- and nucleoside-induced pain following single dose administration. Thus, SPM 927 and related compounds as disclosed in formulae (Ib) or/and (11b) are useful for the treatment of pain during cancer, e.g. bone cancer pain, after treatment with chemotherapy and nucleosides in humans.
